Mas alla de eso, yo nunca levantaria una nota del Telegraph... :PLiving in the Netherlands I haven't heard anything from major news sources, this article quotes "Het Parool", which is an Amsterdam only newspaper. I haven't read anything on "nu.nl" or in "The Volkskrant", both of these are some of the largest news sources here.
Beside that, Geert Wilders, who proposed this originally (according to the article) is an idiot. He's stated before that he wants all Muslims deported, demolish all Mosques, leave the EU, Kick Greece out the EU and was sued last year for discriminating immigrants (although he won that case.)
I wouldn't count on something like this to happen really.
